Missing icons for active windows on the windows taskbar

there are a couple of vertical bars on the taskbar.  There location may determine whether or not you can see the icons.  I would try moving all these vertical bars to the left hand side of the taskbar

Actually I found the answer to another question posted on this same site.  Below is the fix:

The workaround:  Just use the ALT-TAB keys to select the
                 active windows until a IS technician can
                 stop by your pc to fix this issue or you
                 have ran the below procedures.

Fix:
* Left click on the 'Start' button
* Left click on the option RUN
* Type in MSCONFIG and then click on the OK button
* On the MSCONFIG window, left click on the startup tab
* Check to see if pmedia is located in the list of
  startup applications, if so uncheck it by left clicking
  on the checkbox to remove the check mark, then left
  click on the apply button then left click on the OK
  button.  
* If prompted to restart your pc, please do so, if not go
  ahead and restart your pc
* Once your pc has been restarted, log back on
* Double click on the icon 'My Computer' which is located
  on the windows desktop
* Double click on the folder labeled C Drive
* Double click on the folder labeled Program Files
* Double click on the folder labeled Media
* Locate the folder C:\Program Files\Common Files\Media
* Locate the file Uninstal.exe and double click on it
* Follow the instructions for each of the screen until
  you have completed the un-install.
* After the uninstall has completed, if prompted to
  restart your pc, please do so, otherwise restart your pc

We just tried this and it corrected the issue on the pc's
that were having the problem.

Thanks for the comment, I do appreciate it.
